| 摘 要： | 如今生态问题已上升到生态安全的高度,为建设"美丽中国",恢复由连年多代栽种桉树纯林所形成的生态环境,营建桉树人工混交林日益受到人们的重视.混交林对改善立地条件、增强森林防护作用、抗性能力和提高效益等具有重要的意义.本文通过分析我国大片栽植桉树人工纯林所带来的生态问题和国内外桉树人工混交林的试验研究特点,指出我国过去对桉树人工混交林的研究主要侧重于提高经济效益,而对提高生态效益的研究处于一个较低水平,并提出了桉树人工混交林营造技术的要点,以期消除桉树纯林种植所带来的弊端,为营造混交林提供技术指导.

Afforestation Technology of Mixed Eucalyptus Plantations |

| Abstract: | Nowadays ecological problems increasingly threaten ecological security. In order to build a beautiful China and resolve ecological problems caused by planting monoculture plantations of Eucalyptus over successive rotations, increasing attention is being paid to the establishment of Eucalyptus in mixed species plantations. Such mixed plantations can make important contributions to improving site conditions, enhancing forest protection and improving ecological, economic and social benefits that plantations can provide. By analyzing ecological problems created by planting pure species plantations of Eucalyptus and studying the characteristics of mixed species plantations involving Eucalyptus at home and abroad, this study found that research to date from China has focused mainly on increasing the economic benefits whilst largely ignoring improved ecological benefits that mixed species plantations might provide. Following the analyses conducted, recommendations are provided on development of mixed species plantations involving Eucalyptus to eliminate the disadvantages of pure species plantations of Eucalyptus, and some technical guidance is provided for establishment of mixed Eucalyptus plantation. |
